Hey, I had this exact problem a few weeks back already (Old Post). My traffic is being routed through a US edge when I’m based in Europe. My home ISP is Vodafone, but I have the same behavior with my mobile ISP, which is Telekom.
I am again being routed through IAD
. I currently only have one Fly instance running in FRA
.
I also tested some other Fly.io websites, namely worldpagespeed.fly.dev and debug.fly.dev. The problem is, they both behave differently for me. I get the same wrong US edge from worldpagespeed.fly.dev, but debug.fly.dev routes me correctly through CDG
.
I really don’t know what causes this, but it drastically spikes latency to 100+ms when it should be 40ms max.
If more information is needed, I’m happy to provide any to get this resolved.
